passport-litauth

Passport strategy for authentication with LITauth through the OAuth 2.0 API.

Usage

npm install passport-litauth --save

Configure Strategy

The LITauth authentication strategy authenticates users via a LITauth user account and OAuth 2.0 token(s). A LITauth API client ID, secret and redirect URL must be supplied when using this strategy. The strategy also requires a verify callback, which receives the access token, as well as a profile which contains the authenticated LITauth user's profile. The verify callback must also call cb providing a user to complete the authentication.

var LITauthStrategy = require('passport-litauth').Strategy;

var scopes = ['identify', 'email'];

passport.use(new LITauthStrategy({
    clientID: 'id',
    clientSecret: 'secret',
    callbackURL: 'callbackURL',
    scope: scopes
},
function(accessToken, refreshToken, profile, cb) {
    User.findOrCreate({ LITauthId: profile.id }, function(err, user) {
        return cb(err, user);
    });
}));

Authentication Requests

Use passport.authenticate(), and specify the 'litauth' strategy to authenticate requests.

For example, as a route middleware in an Express app:

app.get('/auth/litauth', passport.authenticate('litauth'));
app.get('/auth/litauth/callback', passport.authenticate('litauth', {
    failureRedirect: '/'
}), function(req, res) {
    res.redirect('/secretstuff') // Successful auth
});

Refresh Token Usage

In some use cases where the profile may be fetched more than once or you want to keep the user authenticated, refresh tokens may wish to be used. A package such as passport-oauth2-refresh can assist in doing this.

Example:

npm install passport-oauth2-refresh --save

var LITauthStrategy = require('passport-litauth').Strategy
  , refresh = require('passport-oauth2-refresh');

var litauthStrat = new LITauthStrategy({
    clientID: 'id',
    clientSecret: 'secret',
    callbackURL: 'callbackURL'
},
function(accessToken, refreshToken, profile, cb) {
    profile.refreshToken = refreshToken; // store this for later refreshes
    User.findOrCreate({ LITauthId: profile.id }, function(err, user) {
        if (err)
            return done(err);

        return cb(err, user);
    });
});

passport.use(litauthStrat);
refresh.use(litauthStrat);

... then if we require refreshing when fetching an update or something ...

refresh.requestNewAccessToken('litauth', profile.refreshToken, function(err, accessToken, refreshToken) {
    if (err)
        throw; // boys, we have an error here.
    
    profile.accessToken = accessToken; // store this new one for our new requests!
});

Examples
